8 Channel Seperate Channel Cell Charge and Discharge Grading and Form Machine for 18650 26650
The grading machine is divided into different types: cylinder, aluminum shell and polymer. The internal structure of them is exactly the same, but the clamps are different. The cylinder and the aluminum shell use upper and lower needles to contact, while the polymer uses a gold-plated flat clamp to clamp the tabs for punching. Different channels can be customized according to customer requirements, and the current and voltage are unified, its suitable for mass production.
Cell Grading Machine Functions
1) The graphic operation interface is used to display the voltage, current, time, capacity and other data of each battery, and the corresponding working status and abnormal conditions are displayed in various colors;
2) Battery capacity indication of any section (up to 100 segments);
3) The data points can be recorded according to the change conditions of voltage, current and time to form a complete charging and discharging curve data, and the time interval of curve data points is less than 4 seconds
4) The battery sorting function is carried out under various conditions (capacity, time, open circuit voltage, discharge platform, etc.);
5) Calculate the data of charge ratio, voltage average, discharge efficiency, etc;
6) Operator setting and operation authority;
7) It can display charge discharge curve and cycle diagram;
